what does: cat /proc/bus/input/devices
output?

and can you paste the contents or:
/etc/lirc/hardware.conf

I have set up 4 knoppmyth machines for friends with nova-t's + the silver remote and never had a problem (after figuring it out on my own one obv)

I am also having exactly the same symptoms as Deathwish was.
Does anybody know what to do to fix it?

Sorry ,
That thread does not seem to cover the symptoms I am having or what Deathwish was having either.

My remote is not sluggish or slowly degrading.

There are a significant subset of the keys that work fine
but they are only:
- the 4 arrows
- the OK button
- and the numbers

None of the other buttons appear to work. When I use lirc-reconfig.sh
it doesn't seem to make any difference at all.

I noticed that someone mentioned that these remotes might not even be lirc based but some keyboard kludge.
Would anyone be able to set me on a route of action to reconfigure this sort of thing?

This is based on my post here.
Firstly stop lirc, by:
Then identify what devices are being used by the Nova-T card:
This should return something like this:
So from the lines above, in this case, you can see event2 is the one being used.

So firstly you need to change /etc/lirc/hardware.conf to use eventX, so in my case:

Now you will have to do the setup of your /etc/lirc/lircd.conf by doing:Of course the eventX depends on your setup.
Move the new lircd.conf file to /etc/lirc/lircd.conf .
You need to restart lircd:
Use irw to check that your remote is generating the correct code, then as the mythtv user edit ~/.mythtv/lircrc to match the entries for lircd.conf.

Hope this helps.
